RDN significantly reduced the incidence of ventricular arrhythmias. Representative ECG of electrical stimulation, including sinus rhythm (a), ventricular arrhythmias (b) and (c). Ventricular arrhythmias were less easily induced in RDN group rather than in MI group and Met group (d). (*P < 0.05 vs. Control group; #P < 0.05 vs. MI group; &P < 0.05 vs. Met group).
